Title: Piezo-electric oil level sensor
IPC: G01N27/22
Filed: 1992-03-16
Abstract: PURPOSE:To detect not only the surface level of oil, but also the deterioration of the oil by making an internal and external electrodes to face to each other with a clearance in between. CONSTITUTION:An oil deterioration detecting section 36 which detects the degree of deterioration of insulating oil in the clearance (s) between an internal electrode and external electrode 35 is constituted of the electrodes. Since oil increases in dielectric constant and decreases in AC impedance as the oil deteriorates, the degree of deterioration of the oil can be detected when either the dielectric constant or AC impedance is detected. In addition, since a temperature sensitive element 40 is put in a rubber damper 10, the temperature dependency of the dielectric constant of the oil, temperature dependency of an electronic circuit, etc., can be compensated by detecting the ambient temperature. Thus not only the surface level of the oil, but also the deterioration of the oil can be detected.

Filed: 1986-04-24
Abstract: PURPOSE:To obtain a semiconductor single crystal film, which has a large area and is changed into a single crystal having the same crystalline axis as a substrate, on an insulator by scanning laser beams at an angle of a range to 60 deg. from 20 deg. in the <110> direction of the single crystal substrate. CONSTITUTION:The beam diameter of laser beams having a preset power is adjusted to 100mum, and laser beam are made to irradiate while performing scanning at a scanning rare of 25cm/s the direction (the <510> direction) of an angle of 33 deg. to the <1-10> direction as shown in the arrow in the figure. When one-time scanning is completed laser beams are moved vertically by 50mum in the direction of scanning, and made to perform scanning in the same direction as the previous time. Consequently, when laser beams perform scanning shifted at every 50mum and continue scanning on the whole substrate, polycrystalline silicon 13 on an silicon oxide film 12 grows to a single crystal having a (001) face. Strain generated by the difference of the thermal expansion coefficients of the polycrystalline silicon 13 and the silicon oxide 12 is not stored on the interface of both the polycrystalline silicone 13 and the silicon oxide 12, thus resulting in no inhibition in the growth of a single crystal.

Abstract: PURPOSE: To obtain a chair which can be assembled easily and adjusted freely, by setting up a stopping lever to an adjustable back stopping means, providing a locking mechanism in which the back is slanted when the stopping lever is locked with a fixture to take the nonoperating position, and slanting stops when at the operating position. CONSTITUTION: An adjustable back stopping mechanism 70 is assembled into a back mechanism 16, and a back mechanism 16 is made enable to drive if an actuator button 166 is located in a way that a locking member 76 is set at a nonoperating position, and the base part 114 of a stopping lever 74 engages with a fixture 130. And, the base part 114 of the stopping lever 74 is received in one of grooves 152, since the locking member 76 is moved forward if the actuator button 166 rotates the locking member 76 to locate at the operating position, that is, a locking position. Therefore, the stopping lever 74 can not slant against the back mechanism 16. Since the vine-shaped stopping lever 74 is fixed to the back mechanism 16 when the back mechanism 16 is moved from an upright position to a slanting position, further slanting can be prevented.

Abstract: PURPOSE:To easily make an eye width adjustment by allowing a turning part to turn when a rotating shaft is rotated by an operation member such as a knob outside a casing and then letting an arm contact and leave a couple of lens tubes according to said turn. CONSTITUTION:When the operation knob 14 is rotated, the turning shaft 13 and turning member 15 turns in the rotating direction of the knob. When the turning member 15 turns clockwise, nonturning member ends of the arms 16 and 17 move leaving each other and the lens tubes 3 and 4 are moved in leaving directions together with support plates 7 and 8 to widen the eye width. In this case, the lens tubes 3 and 4 turn on their optical axes to shift support shafts 9 and 10 down in position, so a coupling plate 11 and a pressure plate 12 move down along the turning shaft 13. When the turning member 15 turns counterclockwise, the lens tubes 3 and 4 move approaching to each other to narrow down the eye width. In this case, the coupling plate 11 and pressure plate 12 move up along the turning shaft 13.
